Terraform configuration files

I copied these from a larger repository. However they will work on their own.

terraform {
    required_providers {
        cloudflare = {
            source = "cloudflare/cloudflare"
            version = "4.41.0"
        }
    }
}

// requires the CLOUDFLARE_EMAIL and CLOUDFLARE_API_KEY environment variables
provider "cloudflare" {
}

variable "cf_account_id" {
  type = string
}

locals {
  # This is a sensitive to hide output in plan/apply.
  worker_script_content = sensitive(file(join("/", ["C:/Users/dieffenbache2/Workspace/irs-middleware-iac/CloudflareWorkers", "DRSFailover/dist/worker.mjs"])))
}

# this is an already existing workers script in our account.
# This general setup has worked for other workers
import {
  to = cloudflare_workers_script.drs_failover
  id = "${var.cf_account_id}/dev-drs-failover"
}

resource "cloudflare_workers_script" "drs_failover" {
  name       = "dev-drs-failover"
  account_id = "${var.cf_account_id}"
  content = sensitive(file(join("/", [local.worker_script_content, "DRSFailover/dist/worker.mjs"])))

  # We'll want to add the durable object binding here once it becomes available
  # Request: https://github.com/cloudflare/terraform-provider-cloudflare/issues/1320

Error: The terraform-provider-cloudflare_v4.41.0.exe plugin crashed!

This is always indicative of a bug within the plugin. It would be immensely
helpful if you could report the crash with the plugin's maintaine

Expected output

I expected the cloudflare worker to be imported successfully. I imported several other workers in a similar way with no issues.

Actual output

The provider crashes during import.

Steps to reproduce

The provided main.tf file triggers the panic with a specific cloudflare worker. I haven't encountered the panic with other workers.

The dev_drs_failover cloudflare worker script is a simple worker written in Typescript and using the modules syntax. It has a single durable object binding. I am wondering if the durable object binding is causing the issue.
